RING SPINNING 0R TWISTING DEVICE.

Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed April 17, 1915. Serial No. 22,101.

To all whom it may concern: I

Be it known that I, HERBERT G. Bnnon, a citizen of the United States,residing at Pawtucket, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in RingSpinning or Twisting Devices, of which the following is a specification.

This invention relates to the construction of rotary traveler-ringsemployed in connection with ring-spinning or twisting, and it consistsessentially in certain novel features hereinafter set forth and claimed.

In United States patents numbered 1,075,001 and 1,075,185, issued to meon the 7th day of October, 1913, I have claimed other improvements inapparatus of the general type or character referred to. In theconstruction of former devices of this type rotary ring members weremounted to slide on surfaces of the stationary fellow members, thusmaterially increasing the normal resistance or work when initiallystarting to wind the yarn on the spool.

In the present device the construction is such that in starting therotation of the spool the amount of working friction is materiallyreduced, and so that when the spool has attained its normal speed thecentrifugal force of the rotating members acts to retard thetraveler-ring, thus providing the latter with a substantially uniformnor mal dragging or lagging effect and automatically imparting to theyarn a proper tension and twist while the load is being wound upon thespool.

The essential object of this invention is to provide a rotarytraveler-ring that in starting will move more easily and with lessfrictional resistance than other analogous devices heretofore produced.

In the accompanying drawing Figure 1 represents a top plan view of myimproved traveler-ring device, the ring having a plurality ofindependently revoluble rolls bearing on a relatively stationarybase-ring, portions of the rings being broken away to show the interiorconstruction; Fig. 2 is a corresponding side elevation, also in partialsection; and Fig. 3 is an enlarged crosssection, taken on line 83 ofFig. 2. Broken lines in Figs. 1 and 2 indicate the relation of the spooland the yarn being acted upon.

In my improved device A indicates an annular non-revoluble base-ringhaving what may be termed lower and upper inner flanges a, (4 saidflanges being bored to receive a positively driven spool T, indicated bybroken lines. The member A is also provided with an upwardly extendingouter rim (4 disposed concentric to and integral with the said otherflanges and at right angles to the base flange a and annular recesswhose face a constitutes a track for supporting the rolls D. The saidsurfaces a and Marc adapted to be engaged by the rolls D of the balancedtraveler-ring B, later described. To the rim a is removably secured, byscrews 7', an annular protector-guard 0r cap-ring G for maintaining thetraveler-ring and its members in the normal position and relation. Thedevice may be mounted in a ring-tail Z. See Fig. 2. The underside ofmember C may be engaged by the rolls D.

An inner flange b of the traveler-ring member B conforms to and freelyrotates relatively to said stationary flange'a See Fig. 3, Thedownwardly extending outer flange b of ring B is provided with a seriesof uniformly spaced radial axles or pins cl accurately mounted therein.The axes of the pins 03 are fixed at right angles to the center orlongitudinal axes of the concentric main members A and B. Each pin oraxle is adapted to receive and revolubly support a roll D of steel orother wear-resisting material.

The roll-units are accurately turned and bored so as to rotate true onthe pins and track (1 The ends of the rolls may be made convex orslightly spherical, described from a radius equal to the semi-diameterof the vertical annular surface a The rolls may be interchangeable andreversible by simply making both ends alike in convexity. A slight playor clearance is provided between the ends of the rolls and the adjacentcircular surface a, as indicated at s, and an even greater clearance maybe provided be tween the adjacent surfaces of the flanges a and .7),substantially as shown at 8 Fig. 3. To the upper face of the ring B issecured the traveler-ring has attained its normal a pair of oppositelypositioned eyes or thread-guides E; each eye, as represented, consistingof a-porcelain or other suitable annular member 6 having well-roundedends and a central openinge Said guides, are fixed to the ring by meansof straps e and screws 0 By means of my improvement the rolls D, whichmay be termed tension-rolls, move around bodily with the travelerrring,while at the same time the rolls in engagement with the stationarycircular track a are adapted to turn 7 independently on their axles d.The rolls may move freely endwise or outwardly through centrifugalaction, thereby causing them to engage frictionally with the verticalsurface a of the basering A, and producing a lagging or retarding effecton the traveler-ring and yarn. The said tension or drag, it may beobserved, is due to variations in the speeds of rotation of the spooland the traveler-ring, and the centrifugal force of the'rolls of thelatter.

In the present device it is apparent that the construction is such thatat the instant of starting the traveler-ring its members D are adaptedto roll on the surfaces ofthe stationary member A, thus materiallyreducing the amount of working friction through the employment ofrolling friction. When speed the centrifugal action of members D causesthe latter to frictionally engage the corresponding surfaces of thestationary fellow member, thus producing automatically a suitablelagging or dragging effect to the traveler-ring, which in turn imparts aproper tension to the yarn t :as it is wound on the revolving spool T.The maximum diameter of the spool-loadis indicated at t.

In order to reduce the drag on the yarn leading from the feed-rollstothe'guideeye of the traveler-ring certain of the mounted rolls may beomitted from the corresponding axles at diametrically oppo-- sitepoints,the resulting effect being to lessen the weight and centrifugal action,assuming the other conditions to remain unchanged, thereby producing aspool having a correspondingly lighter yarntension. Obviously,a contrarytension effect, may be produced upon'the yarn by increasing the numberof the rolls. In any event, however,

thering B, including its axles and rolls,-

should be revolubly balanced.

: The device is capable of being lubricated by means of a grease-cupconnected with a plurality of peripherally spaced axles fixed to andprojectingradially outward from the traveler-ring and movable bodilywith it, and anti-friction rolls freely revoluble ,on said axles, saidrolls being in frictional engagement with the 'annular track of thebasering and supporting the traveler-ring.
